Construct Binary Tree from Inorder and Postorder Traversal
Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 题目解析: 用中序遍历和后续遍历还原二叉树。并且二叉树的节点的值没有重复的。这样就好做了,我们知道后序遍历...

leetCode 106.Construct Binary Tree from Inorder and Postorder Traversal (根据中序遍历和后序遍历构造二叉树)
Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 思路:这题和上题类似,前序第一个是根节点,后序遍历最后一个是根节点。其余步骤类似。 代码如下: /** *...

leetCode 105.Construct Binary Tree from Preorder and Inorder Traversal (根据前序遍历和中序遍历构造二叉树)
Given preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 思路:首先根据前序遍历得到根节点,然后在中序遍历中得到根节点的位置,左边的为左子树,右边的为右子树。 然后再...
